Hellsing Ultimate

Alucard, an ancient vampire bound in service to the Hellsing Organization, hunts supernatural threats across England under the orders of Sir Integra Hellsing. When police officer Seras Victoria is fatally wounded during an operation in the village of Cheddar, Alucard turns her into his fledgling vampire rather than let her die. Their missions soon expose Millennium, a remnant Nazi faction engineering an army of artificial vampires to drown London in war.
